Overview
1986 Lancia Delta S4 appears on the official Forza Horizon 6 car list as a B Class (balanced sport) entry in the base roster. This page covers how it tends to drive in its class, where it fits inside the Japan setting, how to think about a starting tune, and which roster entries it naturally compares against.
Background and Forza Horizon 6 context
The Delta S4 was Lancia's Group B rally weapon, with both supercharger and turbocharger feeding a 1.8-litre four-cylinder for over 480 hp in qualifying trim. It won the Lombard RAC Rally in 1985 and the Monte Carlo Rally in 1986 before Group B was banned at the end of that season following multiple fatalities. On the official Forza Horizon 6 car list this 1986 Lancia entry sits in the B Class (balanced sport) bracket inside the base roster, which is the placement players come to this page expecting to confirm against the public source. Inside the same B Class (balanced sport) bracket, the closest comparison roster entries for players are 1984 Audi Sport quattro and 2001 Audi RS 4 Avant, which is the B Class (balanced sport) peer group this car is usually weighed against.
Driving feel in Forza Horizon 6
Delta S4 is Group B's most over-engineered rally car — a 1.8 inline-four with both supercharger and turbocharger for combined 480hp in works rally trim, plus full-time AWD. In B-class events on Forza's mixed surfaces the S4's twincharged powertrain delivers torque from very low rpm; the operating window is narrow and aggressive.
Where it shines
B class is one of the most popular brackets in the Forza community because cars feel quick but balanced. It works for Road racing, Street racing on shorter routes and most casual rivals.
Tuning starting point
Look for tunes that match how you brake. If you brake late, dial in slightly stiffer rear damping. If you trail-brake, soften the front anti-roll bar.
How to get 1986 Lancia Delta S4
This car is listed without an add-on label on the official Forza Horizon 6 source, so we treat it as part of the base roster. Forza Horizon 6 launches on May 19, 2026, and before that date the public Autoshow may not surface every base-roster car yet — players asking 'how do I get this car, it is not in the Autoshow?' on Reddit or the Forza forums usually find the answer is 'wait for launch day or a post-launch update'. After launch, base-roster cars are normally available through credits in the Autoshow, Wheelspins, Festival Playlist rewards, or the in-game showcase that introduces new vehicles.
